使用php将文件上传到服务器

Question

很好，很高兴问候你，

我有一个带有 Angula、Laravel 和 Bootstrap 的项目，我正在创建一个表单，以便能够通过项目的网站将文件上传到服务器，我将此代码放在下面，但它无法正常工作，你能帮我告诉我必须放置的代码或告诉我我失败的地方？

等待您的答复，收到亲切的问候，

非常感谢，

这是在我的 HTML 中

<div class="container">
  <div class="row">
    <form method="post" action="test_act.php" enctype="multipart/form-data">
      <div>
        <span>Choose file</span>  
           <input type="file" name="fileToUpload" id="fileToUpload"><br/>
              <input type="submit" name="fupload" id="fupload">
       </div> 
     </form>
  </div>
</div>

test_act.php

<?php 
include ("test_cls.php");
if(isset($_POST['fupload']))
{
    $dirpath="upload";
    $uploader   =   new Uploader();

    $uploader->setExtensions(array('jpg','jpeg','png','gif','doc','docx', 'pdf'));  //allowed extensions list//

    $uploader->setMaxSize(1);                          //set max file size to be allowed in MB//

    $uploader->setDir($dirpath);

    if($uploader->uploadFile('fileToUpload'))          //txtFile is the filebrowse element name //
    {   
        $suc_file  =   $uploader->getUploadName(); //get uploaded file name, renames on upload//
        echo $suc_file." successfully uploaded";
    }
    else                    //upload failed
        echo $uploader->getMessage(); //get upload error message
}
?>

您的代码运行良好。

但是，您可能会检查：

• 是否创建了上传目录
• 上传目录是否具有所需的权限
• 您的文件未超过定义的 php.ini 上传限制大小
